Iron Series Metal-Organic Frameworks and Their Composite Nanomaterials: Controllable Synthesis and Clean Energy Applications

Iron series (Fe, Co, Ni) metal-organic framework materials (MOFs) have characteristics of adjustable structure, and high specific surface area. Their potential for clean energy applications have attracted widespread research interest. Herein, we summarize different synthetic strategies of iron series MOFs and their composite nanomaterials up to date, including but not limited to hydrothermal method, solvothermal synthesis, and microwave-assisted synthesis. The synthesis tactics of iron series MOF nanomaterials in different dimensions are also within the scope of discussion. Additionally, the derivatives of iron series MOF nanomaterials are involved, with a specific emphasis on their utilization in electrochemical applications. With the deepening of research, the future development of iron series MOFs and their derivatives will focus on improving their stability and scalability, and further optimizing their electrochemical catalysis and energy storage performances. For example, to further improve the stability and specific capacitance of iron series MOFs in lithium-sulfur batteries, supercapacitors and other energy storage devices. At the same time, their catalytic efficiency in hydrogen evolution reaction, oxygen evolution reaction, and other electrocatalytic applications was improved. In short, iron series MOFs and their compositesare expected to become a multifunctional and efficient nanomaterials in the future, bringing innovative solutions to various industries and having broad development prospects.
